SPECIFICATION forming part of Letters Patent No. 543,337, dated July 23, 1 895.

Application tiled September 18. 1894. Serial No. 523,400. (No model.) i

To all whom t may concern: y

1 3e it known that I, WILLIAM DR1EsBAcH,a citizen of the United States, residing at Williamsport, in the county of Lycoming and State of Pennsylvania, have invented a new and useful Pneumatic Tire, ot' which the following is a specification.

My invention relates to pneumatic tires, and particularly to the shoes for use in connection therewith for protecting the inliatable tube; andthe objects in view are to provide simple andeflicient means for strengtheningv or reinforcing the shoeto prevent puncturing by sharp objects or instruments, to provide simple means for securing the shoe to the rim of a wheel, and to vprovide means whereby the iniatable tube may be exposed at any desired point when the same is necessary to facilitate -responding parts in all the iigures of the drawings.

l designates the inflatable tube, inclosed within the shoe 2,'and 3 represents the rim (a portion thereof only being shown) to which the shoe is attached.

The shoe is constructed cylindrical in crosssection and is divided or split at its inner side to form the abutting edges 4, and thesaid edges of the shoe are thickened to form the flat bearing-surface 5 and the opposite shoulders 6, which are spaced from the edges and are slightly undercut or beveled.

Attached to the inner surface of the tread portion of the shoe is one layer or more of leather, forming a shield 7, the edges thereofA being thinned or beveled to avoid forming abrupt shoulders or edges for contact with the surface of the inflatable tube. These strips,which are disposed longitudinally or parallel with the length of the shoe, may be held in place in any suitable or approved manner, one manner of accomplishing the object being illustrated in the drawings, in which is shown a pocket formed of canvas or other fabric or flexible material, as at 8, which is glued or cemented or otherwise secured at its edges to the inner surface of the shoe at opposite sides of the shield.

The means for securing the shoe to a rim consist ot' small clips 9, preferably formed of sheet metal and having upturned terminal flanges or lips 10, which bear against and engage the shoulders 6 at the outer sides of the thickened edges of the shoe. These clips are secured to the shoe by means of small pins 1l passing through said flanges or lips and engaging the shoulders, and the clips are secured to the rim of awheel by means of bolts l2 engaging registering perforations 13 and 14, formed, respectively, in said clip and'rim. When itis desired to repair the rim the tire may be removed by loosening said bolts, and when it is necessaryto gain access at any point to the interior of the shoe it may be accomplished by removing one or more of the clips and separating the edges of the shoe.-

The abovel construction provides for the ready attachment and detachmentof a tire and for the repair or replacement of an inlatable tube; but it will be obvious that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having described my invention,I claiml. The combination with an inflatable tube, of a protective inclosing shoe having its separable edges arranged at the inner side of the tube, clips detachably secured to said edges to hold them in their proper relative positions, and means for detachably securing the clips to the outer surface of the rim of a wheel, substantially as described.

2. The combination with an inliatable tube, of an inclosing shoe having abutting inner edges thickened to form spaced shoulders, clips having upstruck flanges or lips secured to said shoulders, and means for-attaching the clips to a rim, substantially as specified.

3. The combination with an inilatable tube, of an inclosing shoe having thickened abutting edges provided with spaced beveled or under-cut shoulders, clips extending trans.
